System Designer (Heat Pumps, Residential)

About Zero Homes Our mission is to rebuild American communities through healthy, affordable homes.

At Zero Homes, we operate on a simple premise: when you make contractors successful, homeowners win. The current home services industry is fragmented, complex, and opaque, which is frustrating for homeowners and exhausting for contractors. We are changing this by building a home upgrade marketplace that enables a simple, central, transparent process for homeowners and contractors to complete projects.

Through our platform we handle design, quoting, procurement, and customer service, allowing our contractor network to focus on what they do best and make them money: delivering projects. For homeowners, this delivers a predictable, high-quality, and transparent experience—transforming home upgrades from a source of anxiety into a seamless experience.Our vision is to create a world where homeowners and contractors in all 50 states can leverage our platform to execute thousands of projects every week within the next 36 months.

We work by a clear set of values: Be a "can kid," not a "can’t kid": We own our outcomes and go to extraordinary lengths to solve problems. Go fast, be clear: Speed is our advantage, and we sweat the details to deliver an extraordinary customer experience. Customer & Contractor Obsessed: We have a deep, personal understanding of the work to be done. We stay curious about our contractors' craft and the stories of our homeowners. Win, as a team: We are building an iconic business that will reinvent the industry, and will do so together. If you are ready to build a world-class consumer experience that genuinely rebuilds American communities, come build with us.
